the size of your penis isnbt an issue its the way you use it that counts,dont let this become a bigger problem than it needs be.
No on can really help you, your penis is the way it is and that wont change.......its not alway about the size, but how you use it......i was with a guy for a couple years and he didnt have the biggest penis, but the way he made me feel and i loved him, size didn't matter.....size shouldn't matter when you are in love, the size go half way and the love the rest.......this is normal cause guys sometimes compare them self to others guys and think they might not be able to satisfy their mate, but i think you should be fine....
As long as you are a good and attentive lover, your size will not affect anything in a negative way. A woman's vaginal opening is closed at the beginning of sex, and it opens enough to admit the penis but does not gape open. Her clitoris is right at the top front of the vagina, placed in such a way that it would be stimulated by a penis one inch long. Try to relax over the situation, and enjoy her beauty and sexuality, and nature will take its course. Most women would rather have a 4-inch guy than a 10-inch guy, because a huge penis can really hurt.
